problems building git master under MinGW

[Robert Boehne]

Libtoolers,

Although libtool 2.4 and 2.4.2 built fine under MinGW w/ gcc/g++, with 
good test suite results (IIRC 5 fails/ 4 xfails)
I've not been able to get git master to build on this platform.

I worked around this by building on Linux, and scp'ing the doc 
directories contents to the windows 7 machine.
After that the test suite builds.

Thanks,
